Description

Technical Field

[0001] The utility model relates to the technical field of light touch switches, in particular to a positioning structure of a light touch switch. Background Art

[0002] A touch switch, also known as a push button switch, is an electronic switch. Its working principle is to close the circuit by applying a certain operating force, and the circuit is disconnected when the pressure is removed. Most touch switches include a switch body and a push switch arranged above the switch body. In order to effectively fix the position of the touch switch, a positioning bracket is generally installed on the outside of the touch switch. In the prior art, in the patent with publication number CN205264539U, a convex column is used to connect the base and the cover plate, but the sides of the cover plate and the base are not limited, which easily causes the cover plate to deviate from the base, affecting the positioning of the entire base. Utility Model Content

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect in the prior art that the cover plate and the sides of the base are not limited, which easily causes the cover plate to deviate from the base, thereby providing a positioning structure of a touch switch with good positioning effect.

[0004] To this end, the utility model provides a positioning structure of a touch switch, the touch switch includes a shell and a pressing assembly arranged inside the shell, a positioning bracket is sleeved on the outside of the shell, and there are positioning components for connecting the two between the two sides of the positioning bracket and the shell, and the positioning component includes a positioning block arranged on one side of the positioning bracket or the shell and a stamping groove arranged on the other side and adapted to the positioning block.

[0005] Furthermore: the positioning block is arranged outside the shell, the stamping groove is arranged on the positioning bracket, and the positioning block is provided with an inclined surface for guiding the shell to be inserted into the positioning bracket.

[0006] Further: the positioning bracket includes a connecting plate and positioning plates arranged at both ends of the connecting plate, a "["-shaped structure is formed between the connecting plate and the positioning plate and a positioning cavity is formed for accommodating the shell, the stamping groove is arranged on the positioning plate, and the positioning block is arranged on the shell.

[0007] Furthermore: the stamping groove is circular.

[0008] Furthermore: the positioning cavity includes a housing cavity for accommodating the shell and an extension cavity for connecting to an external circuit board, and the positioning piece is also provided with supporting feet for fixing to the circuit board.

[0009] Furthermore: a side of the positioning piece facing away from the connecting piece is provided with an inclined bottom plate capable of contacting the circuit board to adjust the inclination of the shell.

[0010] The technical solution of the utility model has the following advantages:

[0011] 1. The utility model provides a positioning structure of a touch switch, in which a positioning bracket is installed outside the touch switch, and four bosses extend from the top of the shell to be connected to the positioning bracket. However, this connection method results in a low connection strength between the shell and the positioning bracket, and the two sides of the positioning bracket will move. Because this embodiment provides positioning components for fixing the positioning bracket and the shell on both sides of the positioning bracket, during the production process, the shell can be first installed inside the positioning bracket, and the upper end face of the shell can be contacted with the lower end face of the positioning bracket for preliminary positioning, and then the shell and the positioning bracket are placed on a stamping die for processing. There will be a stamping head on the stamping die to stamp the positioning bracket, so that the stamping groove on the positioning bracket is stamped out to abut against the positioning block, thereby realizing the three-position fixation of the shell and the positioning bracket, and greatly improving the connection strength between the shell and the positioning bracket.

[0012] 2. The utility model provides a positioning structure for a touch switch, in which a positioning block is arranged on the side of a shell, and a stamping groove is formed by stamping a positioning bracket. When the stamping groove is formed, the positioning bracket will deform toward the side close to the positioning block, and the deformed part will resist the positioning block, thereby realizing the connection and fixation between the shell and the positioning bracket.

[0024] Example

[0025] The present embodiment provides a positioning structure of a touch switch, which includes a shell 1 and a pressing assembly arranged inside the shell 1. A positioning bracket 2 is sleeved on the outside of the shell 1. Positioning components 3 for connecting the two are provided between the two sides of the positioning bracket 2 and the shell 1. The positioning component 3 includes a positioning block 31 arranged on one side of the positioning bracket 2 or the shell 1 and a stamping groove 32 arranged on the other side and adapted to the positioning block 31.

[0026] The above-mentioned specific improvements are as follows: compared with the prior art, a positioning bracket 2 is installed on the outside of the touch switch, and four bosses extend from the top of the shell 1 to be connected to the positioning bracket 2. However, this connection method results in a low connection strength between the shell 1 and the positioning bracket 2, and the two sides of the positioning bracket 2 will move. Because this embodiment provides positioning components 3 for fixing the positioning bracket 2 and the shell 1 on both sides of the positioning bracket 2, during the production process, the shell 1 can be first installed inside the positioning bracket 2, and the upper end face of the shell 1 is in contact with the lower end face of the positioning bracket 2 for preliminary positioning, and then the shell 1 and the positioning bracket 2 are placed on a stamping die for processing. There will be a stamping head on the stamping die to stamp the positioning bracket 2, so that a stamping groove 32 is stamped out on the positioning bracket 2 to abut against the positioning block 31, thereby achieving three-position fixation of the shell 1 and the positioning bracket 2, greatly improving the connection strength between the shell 1 and the positioning bracket 2.

[0027] On the basis of the above embodiment: the positioning block 31 is arranged outside the shell 1 , the stamping groove 32 is arranged on the positioning bracket 2 , and the positioning block 31 is provided with an inclined surface 4 for guiding the shell 1 to be inserted into the positioning bracket 2 .

[0028] The above specific improvements are: Figure 1-Figure 4 As shown, the positioning block 31 is arranged on the side of the shell 1, and the stamping groove 32 is formed by stamping the positioning bracket 2. When the stamping groove 32 is formed, the positioning bracket 2 will deform toward the side close to the positioning block 31, and the deformed part will resist the positioning block 31, thereby realizing the connection and fixation between the shell 1 and the positioning bracket 2.

[0029] On the basis of the above embodiment: the positioning bracket 2 includes a connecting piece 21 and positioning pieces 22 arranged at both ends of the connecting piece 21, a "["-shaped structure is formed between the connecting piece 21 and the positioning piece 22 to form a positioning cavity 5 for accommodating the shell 1, a stamping groove 32 is arranged on the positioning piece 22, and the positioning block 31 is arranged on the shell 1.

[0030] The above specific improvements are: Figure 3 As shown, the positioning bracket 2 includes a connecting piece 21 and positioning pieces 22 arranged at both ends of the connecting piece 21, and a stamping groove 32 is opened on the positioning piece 22. During the assembly process of the connecting shell 1 and the connecting piece 21, the pressing part of the touch switch is passed through the connecting piece 21, so that the upper end surface of the shell 1 is in contact with the lower end surface of the connecting piece 21. At this time, the shell 1 is located in the positioning cavity 5, and then the stamping grooves 32 are punched out on the positioning pieces 22 on both sides of the connecting piece 21, so that the positioning blocks 31 on both sides of the shell 1 are connected to the positioning pieces 22.

[0031] On the basis of the above embodiment: the stamping groove 32 is circular.

[0032] The above-mentioned specific improvement is that the punching groove 32 can be set to a quadrilateral or a custom shape by the manufacturer. However, during the experiment, it was found that the punching groove 32 punched into a circle has the highest connection strength.

[0033] On the basis of the above embodiment: the positioning cavity 5 includes a receiving cavity 51 for receiving the shell 1 and an extension cavity 52 for connecting with an external circuit board, and the positioning sheet 22 is also provided with a supporting foot 6 for fixing on the circuit board.

[0034] On the basis of the above embodiment: the side of the positioning piece 22 facing away from the connecting piece 21 is provided with an inclined bottom plate 7 which can contact with the circuit board to adjust the inclination of the housing 1 .

[0035] The above specific improvements are: Figure 1 and Figure 2 As shown, the positioning cavity 5 includes a receiving cavity 51 and an extension cavity 52, and the two are interconnected. During the installation process, the shell 1 is first placed in the receiving cavity 51, and then the supporting foot 6 is connected to the circuit board. The extension cavity 52 is used to avoid parts on the circuit board. When it is necessary to adjust the installation angle of the touch switch, the inclined bottom plate 7 can be made to contact with the circuit board to adjust the angle of the touch switch pressing key. When it is not necessary to adjust the pressing key angle, it is only necessary to make the bottom of the positioning sheet 22 contact with the circuit board.

[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
